Gorman on 2000 define Elderly people “The ageing process is of course a
biological reality which has its own dynamic, largely beyond human control.
However, it is also subject to the constructions by which each society makes
sense of old age. In the developed world, chronological time plays a paramount
role. The age of 60 or 65, roughly equivalent to retirement ages in most
developed countries, is said to be the beginning of old age. In many parts of
the developing world, chronological time has little or no importance in the
meaning of old age. Other socially constructed meanings of age are more
significant such as the roles assigned to older people; in some cases it is the
loss of roles accompanying physical decline which is significant in defining
old age. Thus, in contrast to the chronological milestones which mark life
stages in the developed world, old age in many developing countries is seen to
begin at the point when active contribution is no longer possible”.
